The clamping mechanism 2 is arranged on the base 1. The clamping mechanism 2 includes two clamping plates 21 slidably mounted on the base 1. A bidirectional screw 22 is rotatably mounted on one side of the base 1. The bidirectional screw 22 is horizontally arranged. A first motor 23 for driving the bidirectional screw 22 to rotate is fixedly mounted on one end of the base 1. The two clamping plates 21 are respectively sleeved on both ends of the bidirectional screw 22 and are threadedly connected to the bidirectional screw 22. By setting the clamping mechanism 2, when pressing the cardboard, the cardboard is placed on the base 1, and the first motor 23 is started to drive the bidirectional screw 22 to rotate, so that the bidirectional screw 22 drives the two clamping plates 21 to approach each other, so that the clamping plates 21 clamp and limit the cardboard, thereby ensuring the stability of the cardboard during pressing.

[0031] Among them, the top of the base 1 is fixedly connected to the support 11, and a dovetail groove 12 is opened on the side wall of the support 11. A dovetail block 24 is provided at the end of the splint 21 away from the bidirectional screw 22. The dovetail block 24 slides in the dovetail groove 12. Through the cooperation between the dovetail groove 12 and the dovetail block 24, a guiding and limiting effect can be exerted on the other end of the splint 21, which can improve the stability of the splint 21.

[0032] The pressing mechanism 3 is installed on the support 11. The pressing mechanism 3 includes a cylinder 31 fixedly installed on the top of the support 11, a connecting frame 32 fixedly installed at the lower end of the cylinder 31, a connecting seat 33 slidably installed at the bottom of the connecting frame 32, and a pressure roller 34 provided at the bottom of the connecting seat 33. A reciprocating screw 35 is rotatably installed in the middle of the connecting frame 32. The reciprocating screw 35 is arranged horizontally. A second motor 38 for driving the reciprocating screw 35 to rotate is fixedly installed at one end of the connecting frame 32. The connecting seat 33 is sleeved on the reciprocating screw. The rod 35 is threadedly connected to the reciprocating screw 35. By setting the pressing mechanism 3, during pressing, the cylinder 31 can be started to drive the connecting frame 32 to descend, so that the pressing roller 34 is pressed on the surface of the cardboard, and then the second motor 38 is started to drive the reciprocating screw 35 to rotate, so that the reciprocating screw 35 drives the connecting seat 33 to reciprocate horizontally along the reciprocating screw 35, so that the connecting seat 33 drives the pressing roller 34 to roll back and forth on the cardboard, and the cardboard is repeatedly pressed to avoid the situation where the cardboard is partially pressed loosely, thereby improving the pressing quality.

[0033] Among them, the connecting frame 32 is fixedly connected to the guide rod 39 on both sides of the reciprocating screw 35, and the connecting seat 33 is slidably sleeved on the guide rod 39. By setting the guide rod 39, the connecting seat 33 can be guided, making the connecting seat 33 smoother and more stable when moving.

By setting the spring 36 and the limit rod 310, after the pressure roller 34 contacts the cardboard, the spring 36 will be compressed to prevent the cardboard from being damaged by excessive pressure at the moment.

[0035] Working principle: When laminating cardboard, place the cardboard on the base 1, start the first motor 23 to drive the bidirectional screw 22 to rotate, so that the bidirectional screw 22 drives the two clamps 21 to approach each other, so that the clamps 21 clamp the cardboard and limit it. Then, the cylinder 31 can be started to drive the connecting frame 32 to descend, so that the pressing roller 34 is pressed on the surface of the cardboard, and then the second motor 38 is started to drive the reciprocating screw 35 to rotate, so that the reciprocating screw 35 drives the connecting seat 33 to reciprocate horizontally along the reciprocating screw 35, so that the connecting seat 33 drives the pressing roller 34 to roll back and forth on the cardboard, repeatedly laminating the cardboard to avoid the situation where the cardboard is partially lax, thereby improving the laminating quality.
